0 Euro - Technik Museum Sinsheim classique

Oberthur Fiduciaire has produced the bulk of Europe's souvenir zero euro series since the format took off around 2015, and this Sinsheim issue is a straightforward entry in that commercial run. The notes are legal tender in name only — the European Central Bank tolerates but does not endorse them — and their appeal is purely as collectibles sold through museum gift shops rather than as anything approaching monetary instruments.

Sinsheim's museum is notable for its aircraft collection, which includes a retired Concorde and a Tupolev Tu-144 displayed side by side outdoors — the only place in the world where both supersonic passenger types can be seen together.
